  3. Outline • Introduction • 3D Web Basics • Definitions • Applications and motivations • Available Web3D Technologies • Adaptivity for 3D Web sites • Architecture for Adaptive 3D Web sites • Case Study in E-Commerce • Conclusion

  4. Introduction • Given current technological advancements in desktop computing interactive 3D models of objects and 3D Virtual Environments (VEs) can be experienced through the Web, using the hardware that can be found in common, low-cost personal computers. • 3D web content is being deployed in a variety of applications: education & training, ecommerce, architecture and virtual cities, virtual communities and virtual museums • Play video (navaid.avi)

  5. Intro. Cont. • This presentation is designed to introduce you to the concepts and techniques of adaptive 3D Web sites. • It will provide an introduction to 3D Web sites, with an overview of the major application areas and mentioning the main technologies, concentrating on standard ones. • The adaptivity section will provide the context of 3D Web sites by first looking at analogies and differences with respect to Web-based hypermedia, and then discussing the problems of modeling and adaptation. • In the Architecture for Adaptive 3D Web sites it will describe an example of a full architecture for adapting 3D Web content. • A case study will then be considered in the domain of e-commerce. • The conclusion will discuss current research challenges and directions.

  6. 3D Web BasicsDefinitions • Web3D technologies: The languages, protocols and software tools that make it possible to build 3D models of objects and 3D VEs that can be experienced through the Web, using common personal computers • Complex 3D Web content: virtual cities, visualizations of scientific data, and virtual museums. • Web technologies: content (represented in a proper format) is stored on a server and is requested by a client (typically, through HTTP), where it is displayed by a browser, or, more often, by a plug-in for a traditional Web browser. • 3D Web content: can be strongly integrated with existing Web content, both by augmenting Web sites with 3D interactive content (e.g., a 3D model can appear into a Web page together with HTML content) and by displaying most types of Web content (e.g., images, sounds, videos) inside a 3D VE accessible through the Web. • Note: most Web3D technologies neither require nor preclude immersion, and 3D Web content can also be experienced with the input/output devices of today's common personal computers (i.e., CRT or LCD monitor, keyboard and mouse).

  7. 3D Web BasicsApplications and motivations • Learning and Training • E-commerce and Product Visualization • Virtual Museums • Architecture and Virtual Cities • Virtual communities

  8. Learning and Training • Most important application areas for 3D Web sites. • 3D VEs offer the possibility to recreate the real world as it is or to create completely new worlds, providing experiences that can help people in understanding concepts as well as learning to perform specific tasks • Tasks can be repeated as often as required and in a safe environment

  9. L & T Cont. • Employing 3D graphics allows for more realistic representations of subjects or phenomena, offering the possibility of analyzing the same subject from different points of view. • This is important in the medical education domain where 3D reconstructions of parts of the human body

  10. E-commerce and Product Visualization • 3D Web store advantatges if properly implemented: • it is closer to the real-world shopping experience, and thus more familiar to the customer • it supports customer’s natural shopping actions (such as walking, looking around the store, picking up products,…), • it can satisfy emotional needs of customers, by providing a more immersive and visually attractive experience • it can satisfy social needs of customers, by allowing them to meet and interact with people (e.g., other customers or salespeople).

  11. E-Commerce VE Cont. • Play clothing video
